Yes it is an issue with unvac cats, all our cats visit the vet first no matter what and are vac if possible.. However the benefit of Sharns cattery is that she gets alot of people visiting and we have homed a few just by that. Also last year, we hired her cattery and held our open day their and rehomed all our cats in one bright and very sunny afternoon...!!
We supply all of Sharns food (for CP cats and overspill some of her own lodgers) in lieu of cat litter that although we do give her litter is usually never enough.. Also we have to arrange a volunteer to do all the vet trips (this is usually Mark!!) as we think its wrong to burden her with all the vet visits all the time when she is trying to run her business..
We occassional use her for emergency use,,, and pay for an extra pen but its not that common,she does have an isolation pen for preg cats and kitten. Sharn is one of our longest serviing fosterers and she is fab!
